Power analyser with Ethernet and RCM
Many UMG measuring devices have their own memory containing typical recording ranges of up to 2 years. Recording is freely configurable. A 128 megabyte memory can record around 5,000,000 values.
The alarm management feature in GridVis® monitors all measurement parameters captured by the UMG measuring devices. It comprises escalation management, a logbook function and user management for individual notifications by e-mail, dialogue box on the monitor, etc.
In addition to monitoring effective values, short term interruptions and transients, as well as communication with the measuring devices can also be monitored.
Powerful RCM residual current monitoring already detects leakage currents in their initial stages before they cause system failures or even fires. It is already integrated in certain UMG measuring devices. The measuring current transformer that is required can be installed manually at a later date if required. Continuous RCM monitoring increases the system safety and availability significantly. In specific applications such as the data centre, residual current monitoring is essential due to the high availability requirements.
Measuring devices homepage
The web server for the measuring device provides a wide range of data in a user-friendly format. The user does not have to install any software on their PC; a conventional web browser is all that is required. The user enters the measuring device IP address in the browser's URL bar and the measuring devices homepage is displayed on the screen. In addition to the modern homepage, APPs are available for an extended range of functions.
The Ethernet Modbus gateway can be used to easily include the Modbus RTU devices that are connected to the master device as slaves in an Ethernet architecture. This is also possible via a Modbus RTU interface for devices with identical file formats and matching function codes.
BACnet is one of the most important communication standards for building technology, mainly due to its compatibility with the most diverse hardware and its uniform communication with devices from various manufacturers. As soon as a UMG measuring device has received its BACnet ID and is integrated into the network, the system recognises it and displays it in the browser. This makes configuration very easy.
Areas of application
- Measurement, monitoring and checking of electrical characteristics in energy distribution systems
- Recording of load profiles in energy management systems (e.g. ISO 50001)
- Acquisition of the energy consumption for cost centre analysis
- Measured value transducer for building management systems or PLC (Modbus)
- Monitoring of power quality characteristics, e.g. harmonics up to 40th harmonic
- Residual current monitoring (RCM)
